CAR-WHEEL.

EPECIPICATION forming part of Letters Patent No. 359,174, dated March 8, 1887.

Application filed September 2, 1886. Serial No. 212,533. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE PEACOOK, a citizen of the United States, residing at Selma, in the county of Dallas and State of Alabama, have invented certain new and useful Improve ments in Oar-wheels, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in self-lubricating car-wheels, and has for its objects to simplify the construction and lessen the cost of this class of wheels, and at the same time provide a wheel which will utilize all the oil placed in the reservoir. These objects I attain by the construct-ion shown in the accompanying drawings, and which will be hereinafter fully described and claimed.

In the drawings, Figure l is a side elevation of a car-wheel provided with my improvements. Fig. 2 is a longitudinal and Fig. 3 a cross section of the hub. Fig. 4 is a detail perspective view of the wedge, and Fig. 5 is a detail perspective view of the valve.

Referring to the drawings by letter, A designates the hub, which is composed of two-circular walls, A A, and suitable side walls, with the annular oil-chamber between them. The inner wall, A, forms a sleeve, within which the axle is secured, as will be understood, and is provided with a nipple, a, projecting into the oil-chamber, as clearly shown in Figs. 2 and 3. A lug, a, is also formed on the wall A to one side of and in line with the nipple a, the purpose of which will be hereinafter explained.

The outer wall, A, of the reservoir is formed with an opening, a, which extends across the entire width of the hub, and is directly over the nipple a and luga. This opening is provided for cleaning the hub. The wall A is also provided with two parallel extensionwalls, 0 O, which are connected by a bridge, 0, from the middle of which one of the spokes of the wheel extends to the rim. These side walls, 0 C, and bridge 0' form a protectingchamber for the opening a and its cover and cover-securing devices.

D is the cover for the opening a". .It rests on shoulders d, formed on the wall A of the hub, and is provided with packing, as shown in the drawings, to prevent the escape and waste of oil. The under side of this cover has formed thereon a stud or projection, d, which enters the nipplea and directs the oil into the same, through which it passes to the axle. The cover D is also provided near one end with twin openings, through which the oil is supplied to the annular reservoir. This opening is closed by a valve, E, the construction of which will be readily understood. It consists of a metallic plate, 6, of suitable size and shape, provided on its upper face with packing, as shown in Fig. 2. A lug, -c, is cast on the under face of the plate 6, and when the valve is in proper position this lug e is directly over the lug a on the inner wall of the oil-reser- A coiled spring, E, is held by its opvoir. posite ends passing around the lugs e and a, respectively, and holds the valve to its place. On the upper face of the plate 6, I form twin lugs E E, which fit snug in the before-mentioned openings in the cover and prevent side movement of the valve. One of these lugs, E is projected farther from the plate 0 than the other one, and its end is made angular, so as to be readily engaged by a wrench in operation, as will be presently explained.

To prevent the displacement of the cover D by the spring E, I provide the wedge F, which rests upon the cover and works between it and the bridge 0. The wedge extends entirely across the chamber between the side walls, 0 C, and consists of two side bars, f f, connected by a cross-bar, f, as shown. The side bars, ff, are provided at their rear ends with shoulders f, projecting inward, against which a nut, G, on the retaining-bolt G rests. The side walls, 0 C, are provided with offsets a, and a washer, G", bears against these offsets. The upper surface of the cover D is inclined, except at its rear edge, which forms a shoulder to support the washer G The retaining-bolt is passed through this washer and between the shoulders f f and its screwthreaded end made to engage the nut G, previously placed in the recess of the wedge. The bolt then being turned will draw the nut toward its head, which action will cause the nut to bear against the shoulders f and the wedge will consequently ride up the inclined surface of the cover D and secure it in position, as will be readily understood.

In operation the oil or other lubricant is placed in the annular reservoir B, and passes through the nipple a to the axle. As the wheel revolves, the oil is splashed against the cover and into the nipple, and also collects on the lug d, down which it passes into the nipple, thus insuring the use of all the oil. WVhen it is desired to refill the oil-reservoir, a wrench -is placed on the angular end of the lug E on the valve E and sufficient pressure applied to'overcome the tension of the spring E and push the valve downward far enough to allow the lug E to pass under the cover. A quarter-tur-n is then given the wrench, which will cause the lug E to pass under the cover, leaving the opening clear and admit-ting the oil. When the reservoir has been filled, the valve 'is turned back and closes the opening.

by the wedge and engaged by the bolt, whereby the cover is held in place, substantially as shown and described.

3. The combination, with the oil-reservoir having an apertured outer wall, and having its inner wall provided with a nipple, of a cover closing the aperture in the outer wall and having a stem or lug on its under side, which enters the nipple in the inner wall of the reservoir, substantially as and for the purposes set forth.

4. The combination, with the reservoirwalls, of a valved cover closing an aperture in the outer wall,the valve, and a coiled spring held in position by lugs on the inner wall of the reservoir and the under side of the valve,- whereby the valve is normally held closed, substantially as specified.

5. The herein described and shown valve, composed of a metal plate having a lug on its under side and a pair of lugs of different heights on its upper side, the larger one being adapted to be engaged by a wrench, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

I GEORGE PEACOGK.
